Description from Wikipedia

Mahonia nervosa, commonly known as dwarf Oregon-grape, Cascade Oregon-grape, or dull Oregon-grape, is a flowering plant native to the northwest coast of North America from southern British Columbia south to central California, with an isolated population inland in northern Idaho. It is especially common in second growth, Douglas-fir or western redcedar forests, making use of those pools of sunlight that intermittently reach the ground. Some authors place the genus Mahonia within the genus Berberis.
